My sense is that Japanese youth are drawing their conclusions about America from the limited information given to them via movies and what the news media in their country presents to viewers.

I’m Japanese and one of my cultural shocks in America was that many people said "bless you" to me when I sneezed, even though I was a stranger to them. In Japan people don’t talk to others. I had heard "bless you" from my american friends so I knew what that meant, but I didn't expect that people use it to non-friends.

I was smiling throughout the video, I was not expecting their view of the U.S to be this positive. As an American, there is soooo much that we can learn from Japan. I love Japanese culture.

I am an American who is living in Japan. It's a bit surprising but I am happy to hear all these young people say they really like America, especially because the Europeans are always putting us down. I love living here, and Japan is such a beautiful and interesting place; it has been so much fun to learn about Japanese culture and to try and speak the language!
